Air Force accepts KC-46A Published Jan. 10, 2019 By Secretary of the Air Force Public Affairs ARLINGTON, Va. (AFNS) -- The Air Force accepted the first KC-46A Pegasus tanker from The Boeing Company Jan. 10. This is a major milestone for the next generation tanker and will allow Airmen to begin operational testing and flight training. The Air Force has identified, and Boeing has agreed to fix at its expense, deficiencies discovered in developmental testing of the remote vision system. The Air Force has mechanisms in place to ensure Boeing meets its contractual obligations while initial operational testing and evaluation continues. The formal delivery ceremony at McConnell Air Force Base, Kansas, will occur as early as late January.
